Missing Lacquer Detector

IS641 / IS651

Protects machinery and product against problems caused by missing lacquer on sheets

A fully self-adjusting and self-calibrating sensor with no need for operator intervention

IS641 / IS651 Missing Lacquer Detector


  • Self-adjustment and self-calibration
  • User-defined response to reject signal for missing lacquer
  • A heartbeat signal for every sheet
  • Make effective process improvements
  • Promote better operator training
  • Increased plant efficiency

Both IS641 and IS651 sensors works with all white coloured lacquers/varnishes. The IS651 also works with clear varnishes.

Extra Costs from Missing Lacquer

If sheets or can stock get through the process in an uncoated or partially coated state, they can potentially cause serious problems: either can corrosion after filling or blunting of the tooling on a DRD press.

Risk Reduction

It is now possible to reduce these risks by detecting uncoated sheet or can stock at line speed. The IS641 & IS651 sensors protect machinery and product against the problems caused by missing lacquer on blank sheets.

Single or Double Sided

The IS641 or IS651 sensor can be fitted singly for sheet normally coated on one side, or with a second, opposing sensor for complete protection where sheets are coated on both sides.

Self-Adjustment and Self-Calibration

The Missing Lacquer Detector is a fully self-adjusting and self-calibrating sensor with no need for operator intervention. The sensor automatically detects when a changeover occurs and learns the new lacquer characteristics.


On lacquering lines

  • At the outfeed of the wicket oven
  • At the outfeed of the coater

On DRD can lines:

  • At the entrance of the press
